APPARATUS FOR CHANGING THE TEMPERATURE OF LIQUIDS.

To all whom it may concern:

Be it known that 1, PAUL JOSEPH CAR- TAULT, a citizen of the French Republic, and resident of 147 Boulevard St. Germain, Paris, France, have invented a certain new and use ful Apparatus for Changing the Temperature of Liquids, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an apparatus for changing the temperature of liquids by the use of another liquid of a difierent temperature, the two liquids being passed on the opposite sides of a conducting medium separating them.

In the annexed drawing Figure 1 shows a transverse section of the apparatus; Fig. 2 is a longitudinal sectional view of one end of the apparatus, and Fig. 3 is a longitudinal sectional view of the other end of the apparatus.

The apparatus comprises an outer tube 10 and a central tube 11. These are placed one within the other so as to leave a space 12 for the passage of cold water While hot water is passed through the central tube. In order to support the tubes casting l4: and 15 are provided at opposite ends of the tubes. One of these, the casting 14, is provided with a shouldered opening 17 adapted to receive the tube 11 and to discharge the hot water thereinto. This casting is also provided with a larger opening 18 surrounding the tube 11 and communicating with the space, the outer tube 10 being held in place by means of a packing plate 19 embracing the larger tube and removably bolted to the cast-ing 14, a passage 20 in the casting 14: conducts the cold water from the larger opening 18 and the space 12. The other casting 15 is provided wit-h a larger shouldered opening 21 directly receiving the tube 10 and a passage 22 directly communicating with said tube, the tube having a cut-out place 23 for this purpose. The outer end of the opening 21 is provided with a stufiing box 24 removably receiving a shouldered sleeve 25, which in turn receives the tube 11 and conducts the Water therefrom.

In the interior of the central tube 11 is removably placed a plate 26 twisted in helical form which serves to force the liquid molecules to make a gyratory movement impinge upon the sides of the tube, through the Specification of Letters Patent.

action of centrifugal force thus facilitating caloric exchanges with the water in the space 12. Staggered plates 27 deflect the water from side to side in the space 12 and thus also facilitate the caloric exchange.

It is understood that it is substantially immaterial what liquid or which pipe is used for the heat receiving or the heat giving liquids, Whether the apparatus be used for cooling, warming, or in which direction either liquid travels.

All of the parts of the apparatus are removable, thus facilitating cleaning and reair. p I claim as my invention:

1. In an apparatus for changing the temperature of liquids, the combination of a central tube for conducting the liquid, a removable helical plate in said tube, an exterior tube spaced from and receiving the central tube, a casting at each end of the central tube and having a small opening receiving the end of the central tube, a larger opening receiving the exterior tube and a lateral opening communicating with the larger opening, said tubes being removable therefrom, and means for holding the tubes in spaced relation.

2. In an apparatus for changing the temperature of liquids, the combination of a central tube for conducting the liquid; a removable helical plate in said tube; an exte rior tube spaced from and receiving the central tube; a casting at each end of the central tube and each provided with a smaller shouldered opening receiving the adjacent end of the central tube, and with a larger opening concentric with the smaller opening and receiving said exterior tube, each casting being provided with a lateral opening communicating with the exterior tube, one end of the exterior tube being provided with a side opening registering with the adjacent lateral opening; a removable packing means between one end of the central tube and the adjacent smaller openings, and a removable packing means between the other end of the exterior tube and the adjacent larger opening.

In witness whereof I have hereunto set. my hand in presence of two witnesses.
